AI agents use timeline_item_fusion to create or update resources in DaVinci Resolve MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DaVinci Resolve MCP environment.
An AI agent can call timeline_item_fusion faster than any human can review — one bad instruction and it creates or modifies resources in DaVinci Resolve MCP by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access timeline_item_fusion gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DaVinci Resolve MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for timeline_item_fusion:
{
"version": "1",
"default": "deny",
"tools": {
"timeline_item_fusion": {
"limits": [
{
"counter": "timeline_item_fusion_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}timeline_item_fusion stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

timeline_item_fusion. It is categorised as a Write tool in the DaVinci Resolve MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DaVinci Resolve MCP server in PolicyLayer and add a rule for timeline_item_fusion: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DaVinci Resolve MCP. Nothing to install.
timeline_item_fusion is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the timeline_item_fusion rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for timeline_item_fusion. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
timeline_item_fusion is provided by the DaVinci Resolve MCP server (samuelgursky/davinci-resolve-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
